How often should you use copper sulfate in a sewer line?
To be most effective, copper sulfate should be added to the sewer at the first indication of root entrance into the system whether your house plumbing is con- nected to a sewer line or a septic tank. A small amount added each day for a two-week period would probably be more effective than a large amount all at once.
How long does it take for copper sulfate to work?
The treatment will likely cause a sudden, algal die-off causing an oxygen depletion that could result and the dead algae decay and the fish will suffocate. Treating only one third of an area at over 48-72 hours will help avoid crashing your oxygen levels.

Does copper sulfate kill algae?
It doesn’t treat the causes of algae in your pond. When it is applied to an infected water location it can treat only the visible symptoms of algae. Instead of targeting the nutrients that cause the algae to grow in the first place, it only targets algae itself. For this reason, copper sulfate becomes ineffective—it kills the algae, which then sinks to the bottom of the pond where it decays and releases additional toxins which can create more blooms, essentially resulting in a larger problem than you started with.
Is copper sulfate toxic to humans?
